I've lived in this apartment for about a month now, so imagine my surprise when you show up at my door, looking for the former tenant, your ex-girlfriend. You really look like you need to talk when you find out she moved and no one told you about it, so I invite you in for a chat. You slowly tell me a bit about the issues you two had and, well, a couple of the things you mention are things I may be able to help you with. Being older and a bit more experienced in certain things has its advantages, after all. You seem like a sweet guy, and even if this girl didn't see it, the next one might, so giving you a bit of a confidence boost in the bedroom, and a really good time in the process, may just be what you need to feel a bit better. It's worth a shot, isn't it?
